4. Australian climate change adaptation for forestry: current
activities and future needs
Michael Battaglia
5. Australia is dry and getting drier
…with consequences for our forests
1950 - 2008 1970 - 2008
6. With drying comes fire risk
By 2050, the percent change in the number of days with Very
High or Extreme fire weather are:
• Number of ‘Very High’ fire danger days: +20-100%
• Number of ‘Extreme’ fire danger days: +100-300%
Lucas et al., 2007
7. Regional forest carbon stocks and fire
impacts: a shift?

8. Forest fires and water supply
Wildfires in 1939 have decreased stream flows to Melbourne by about 300
GL per year (40%) due to increased forest water use in just 65,000 ha of
regenerating forest.

On the increase – in Australia and elsewhere

Carbon markets and land-use change
Profitability of reforestation of cleared landscapes for carbon sequestration, expressed as equalised annual equivalents (EAE), under a
carbon price of $20/t of CO2-e and the baseline commodity price scenario. Carbon plantings are economically viable when EAE > 0. The
tree systems modelled are: a) Eucalyptus globulus; b) Eucalyptus cladocalyx and Eucalyptus camaldulensis blend; c) Eucalyptus kochii,
and ; d) mixed environmental plantings. Crossman et al. 2010
15. National response .. some examples
• COAG National climate change action plan
• Climate change and forest action plan
• Support research to address major knowledge gaps (FFICCRF,
NCCARF)
• Other national response
• National Biodiversity Conservation Strategy 2010-20
• National water initiative and complementary state legislation
• Sustainable yields studies and MDBC irrigation changes
• Black Saturday Royal Commission Recommendations
16. Framework for what we do (in production
forestry research)
• Better, more useful vulnerability assessments
– not climate-centric but decision-centric
– but has to be based on understanding forest
functioning as well as human systems
• Identify and build adaptive capacity
• Explore adaptation options and their different
dimensions
• Social science to better understand adaptation
decisions (barriers, synergies)
• Work with industry and policy partners to develop
pathways to adoption

production and carbon forestry)

19. TRANZFOR: where we have been
• WP 1 - Genomics and tree breeding strategies
S,I • Virtual gene project (Wu-Cullity)
C • Altitudinal variation in water use Nothofagus (Bresson)

E Use Efficiency (WUE) and discrimination against Carbon 13 (Δ13C)
(Douthe-Warren)
• WP 2 - Forest Models
C • Pinus pinaster (Fontes-Almeida)
C,I • Silvopastoral models (Battaglia-Palma)
C,I • Fast growing plantations and water (White-Cassella)
